Pros: - Supports all popular channels like WhatsApp, Telegram, VK, OK, and others. - Has integrations with well-known CRMs: Bitrix24, amoCRM, Yclients, and more. - Allows for cascading mailings. - Low price. Cons: - Limited number of additional features. - Lacks some communication channels. Overall, this is a great option for standard mailings across popular channels. The cost is low, the setup is simple, and it's convenient to use. However, if you need something more complex (excluding cascading mailings), it won't work. It also lacks the ability to send messages on some social networks and messengers.
